HYDROGEN SUSTAINABILITY & SUPPLY CHAIN | VOGT CTE

The sustainability of the hydrogen supply chain from production to generator describes the properties and conditions that can make hydrogen a sustainable energy carrier. At its core, it is about how hydrogen can enable renewable energy to be stored, transported, and used in versatile ways, thus contributing to a climate-friendly energy supply.

Hydrogen holds the fundamental potential to store renewable energies in chemical form. Surplus electricity from wind and solar facilities can be converted into hydrogen through electrolysis. This allows energy to be utilized in a time- and space-decoupled manner – a central element for an energy system with a high share of fluctuating renewable sources. This capability for long-term storage distinguishes hydrogen from many other energy carriers and gives it a special sustainable relevance.

Another sustainability factor lies in its emission-free usage. When converting hydrogen into electricity or heat, for instance in generators or fuel cells, neither CO₂ nor pollutants are produced. This makes hydrogen particularly suitable for applications where local emissions must be avoided, such as in sensitive environments or in emergency power areas.

Additionally, hydrogen enables a cross-sector coupling of energy generation, industry, mobility, and electricity supply. As an energy vector, it can be used where direct electrification faces technical or economic limitations. This flexibility makes hydrogen an important link in a sustainable overall system and increases the efficiency of renewable energy use across various application fields.

The sustainability of the hydrogen supply chain is also strengthened by its scalability and system integration. Production, storage, transport, and utilization can increasingly be aligned with renewable energy sources and optimized gradually. With growing infrastructure, more efficient electrolyzers, and longer-lasting components, the ecological overall balance improves continuously.

In summary, the sustainable strength of hydrogen does not lie in a single process step, but in its ability to functionally connect a climate-neutral energy system. When hydrogen is produced based on renewable energies, efficiently integrated into the supply chain, and purposefully utilized, it has the potential to make a long-term and substantial contribution to sustainability, supply security, and decarbonization.

PRODUCTION – WHERE DOES THE HYDROGEN COME FROM?

This is the crucial sustainability lever.

Green Hydrogen

Electrolysis with electricity from renewable sources
Very low CO₂ emissions
High electricity demand → Availability is crucial

Blue Hydrogen

Natural gas + CO₂ capture (CCS)
Lower emissions than grey, but not emission-free
Dependence on fossil fuels remains

Grey Hydrogen

Natural gas without CO₂ capture
High emissions → not sustainable

Sustainability question:

What are the CO₂ emissions per kg of hydrogen?

STORAGE – HOW IS HYDROGEN STORED?

Hydrogen is often difficult to handle:

Compressed (350–700 bar)

High energy demand
Material stress on tanks

Liquefied (−253 °C)

Very energy-intensive
Evaporation losses

Chemically bound (e.g., ammonia, LOHC)

Easier transportation
Additional conversion losses

Sustainability question:

How much energy is lost in storage?

HYDROGEN IS CONSIDERED AN IMPORTANT ENERGY SOURCE OF THE FUTURE

Hydrogen is considered an important energy carrier for the future, but it is only truly environmentally friendly if it is sustainable in all three areas: production, transport, and storage, as well as utilization.

The sustainable production of hydrogen occurs through the electrolysis of water using electricity from renewable energy sources like wind or solar power. In this process, water is split into hydrogen and oxygen without the emission of carbon dioxide. Life cycle assessments demonstrate that green hydrogen produces almost no CO₂ emissions, whereas conventional production from natural gas releases significant amounts of CO₂. Real electrolysis plants have already shown that hydrogen can be produced completely climate-neutral when solely renewable energy is used.

Transporting and storing hydrogen can also be achieved sustainably. Hydrogen can be efficiently transported via pipelines, sometimes even using retrofitted natural gas lines. Studies indicate that energy losses during this transport are lower than those occurring when electricity is transmitted over long distances. For storage, pressure tanks and underground salt caverns are among the utilized methods. Measurements confirm that hydrogen can be stored in such facilities over extended periods with very minimal losses. If renewable energy is used for compression, cooling, and transport, additional emissions are also nearly negligible at this stage.

The sustainable use of hydrogen primarily takes place in fuel cells. In this system, hydrogen reacts with oxygen to form water, producing electrical energy and heat. The only byproduct is water, with no carbon dioxide or other pollutants created. Measurements in practical operation confirm that fuel cells operate completely without emissions. Additionally, they achieve a high efficiency that is significantly greater than that of conventional combustion engines. Vehicles, buildings, and industrial facilities using fuel cells are already demonstrating the practicality of this technology.

In summary, hydrogen is sustainable when produced with renewable energy, transported and stored efficiently and with low emissions, and ultimately utilized cleanly. Only the interplay of all three areas makes hydrogen a true building block for a climate-friendly energy supply.

EXAMPLES OF HYDROGEN APPLICATIONS

Example 1: Green Hydrogen from Wind Energy for Power Supply
In wind-rich regions, excess wind power is used to split water into its components, hydrogen and oxygen, through electrolysis. This hydrogen is stored and later converted back into electricity in fuel cells. Proof: Since both the production and electricity generation are based entirely on renewable energy, the entire process emits no CO₂. Measurements show that water is the only reaction product.

Example 2: Hydrogen Trains in Regional Transport
On railway lines without overhead lines, trains are powered by fuel cells. The required hydrogen is produced using renewable electricity and supplied locally. Proof: Emission measurements show that the trains do not emit CO₂, nitrogen oxides, or particulate matter. This proves a completely emissions-free operation.

Example 3: Building Energy with Hydrogen Fuel Cells
Residential and commercial buildings utilize hydrogen fuel cells for simultaneous electricity and heat generation. The hydrogen comes from renewable electricity generation. Proof: The overall efficiency is significantly higher than that of conventional heating systems, while no pollutants are released locally. The exhaust consists only of water.

Example 4: Sustainable Storage in Salt Caverns
Large quantities of green hydrogen are stored in underground salt caverns to keep energy available over weeks or months. Long-term measurements show very low storage losses. Since no chemical transformation takes place and renewable energy is used, no additional emissions are produced.

Example 5: Industrial Production Without Fossil Fuels
In energy-intensive industrial processes, green hydrogen replaces fossil fuels such as coal or natural gas, for instance, in high-temperature processes. Emission measurements show a drastic reduction in CO₂ emissions, as hydrogen does not burn during use but only reacts with oxygen to form water.

These five examples demonstrate that hydrogen can already be used sustainably today if its production, storage, transport, and utilization are consistently aligned with renewable energy.

THE SUSTAINABILITY OF HYDROGEN COMPARED TO OTHER FORMS OF ENERGY

The sustainability of energy forms is primarily assessed based on three criteria: climate impact, resource availability, and environmental burden. In comparison to fossil and renewable energy forms, hydrogen plays a unique role as it is not a primary energy carrier but rather an energy medium for storing and utilizing energy.

Comparison with fossil energy carriers (coal, oil, natural gas)
Fossil energy carriers produce significant amounts of carbon dioxide and other pollutants like nitrogen oxides, sulfur dioxide, and particulate matter during use. Additionally, they are limited in availability and their extraction harms the environment and climate.
Green hydrogen, in contrast, is considerably more sustainable as it produces no exhaust gases during use and can be generated from renewable electricity. While fossil energy carriers contribute directly to global warming, hydrogen allows for nearly climate-neutral energy conversion.

Comparison with renewable energies (wind, sun, water)
Wind, solar, and hydropower are very sustainable since they generate electricity directly without CO₂ emissions. However, their disadvantage lies in fluctuating availability. Hydrogen offers an advantage here because excess renewable electricity can be stored and utilized flexibly over time. Compared to direct electricity from renewable sources, hydrogen is less efficient due to energy losses occurring during conversion, storage, and reconversion. Therefore, hydrogen is primarily sustainable as a complement, not as a substitute for renewable energies.

Comparison with battery storage
Batteries enable highly efficient short-term electricity storage but require limited raw materials such as lithium, cobalt, or nickel. Their extraction is often associated with environmental and social issues. Hydrogen is better suited for long-term storage of large energy amounts and for applications with high energy demand. It is particularly sustainable where batteries reach their technical or ecological limits.

Comparison with nuclear energy
Nuclear energy produces little CO₂ during operation, but it is controversial due to radioactive waste, accident risks, and very long disposal times. Hydrogen derived from renewable energies generates no hazardous waste and is based on nearly infinite resources like water and electricity from sun or wind. Thus, hydrogen is more environmentally friendly in the long term, although it is currently more costly and energy-intensive to produce.
